🔹 Product Description
HXK rotary shell pump, also known as pitot tube pump. It is developed based on new theoretical analysis, design, and manufacturing breakthroughs, introducing a new concept where the vane, shell, and liquid rotate synchronously.
The rotating drum and rotor cover (impeller and liquid) move synchronously, eliminating disk friction losses common in small-flow, high-lift centrifugal pumps or multistage pumps. This results in much higher efficiency compared to traditional high-speed pumps.
Key advantages include:
- Extended Seal Life: The seal only withstands inlet pressure.
- Durable Bearings: Bearings bear minimal axial and radial forces and remain unpolluted by leaking media.
- Stable Performance: Features a continuous rising performance curve from maximum flow to the closing point.
- Low Maintenance: Fewer wearing parts (mainly mechanical seals and O-rings) with high interchangeability.
🔹 Frequently Asked Questions (FAQ)
What is an HXK rotary shell pump (Pitot tube pump)?
It is a high-tech centrifugal pump where the casing and liquid rotate together, utilizing a stationary pitot tube to collect high-pressure fluid, offering superior efficiency for high-lift requirements.
What makes this pump more efficient than multistage pumps?
Because the liquid and impeller rotate synchronously, the large disk friction losses found in traditional high-speed or multistage pumps are significantly reduced.
What industries are best suited for the HXK series?
It is widely used in power generation (boiler feed), paper manufacturing (high-pressure cleaning), and petrochemical processes for hydrocarbon transport.
How does the design improve mechanical seal life?
The mechanical seal is positioned to only withstand the pump's inlet pressure rather than the full discharge pressure, leading to a much longer service life.
Is the performance of this pump stable?
Yes, the performance curve is continuously rising from maximum flow to the shut-off point, ensuring stable hydraulic performance across its operating range.
What materials are available for corrosive media?
The pumps can be manufactured using SS304, SS316, SS316L, Titanium, Monel, 2205, and CD4mc to handle various chemical and corrosive applications.
